I have a W reg 2.0l petrol Alhambra.Diagnostic said HALL 55 Sensor Failure so I replaced the distributor & crank sensor.
Code was zero'd but has returned as HALL 55 again.AARRGG
Engine when driving wont allow acceleration over 4,500 RPMs,
If stationary this is normal(4,500 RPM's) stops damaging engine.
Doing about 20 mpg so very uneconomical.Somebody said change cam position sensor, can't find it as Haines use Ford engine and mine being a volkswagon.Running out of patience,time and money.Can any one PLEASE help as this is DRIVING me mad,no pun intended !

had this problem and was about to buy a new distributor but saw an item on one of the forums and checked the ignition timing.
it was a tiny bit out and when set up right it cured the problem.it apears the hall sensor gap is small and if the timing is set up wrong the gap is not in the right place and thows up a fault

I have an S reg alhambra with the exact same problem and it does my head in too. If i try overtaking i am limited at 4500 revs and it costs an absolute fortune in petrol so if you get an answer to this problem please please please tell me the answer
